The Alexandra Bridge is a steel truss cantilever bridge that was constructed from 1898 to 1901 and is an interprovincial crossing that connects the cities of Ottawa, Ontario and Gatineau, Quebec, lying on either side of the Ottawa River. The bridge carries 18,000 vehicles per day composed of a mix of some trucks, but mainly buses and light vehicles. The total length of bridge is 575 m and the bridge was rehabilitated at several occasions since it was put in service in 1901. The Alexandra Bridge was painted entirely in 1995-96 and it has been observed over time that corrosion and deterioration does not progress at the same rate on the different parts of the structure because of the difference in environmental exposure conditions of the bridge components. Areas located below the travelled deck are prone to more exposure to road salt de-icing and debris accumulation. Therefore, the corrosion and deterioration rates progress more quickly below the deck than above the deck. Some parts of the Page 1 of – de 10 N° de l’invitation - Solicitation No. N° de la modif - Amd. No. Id de l’acheteur - Buyer ID EQ754-201337/A 003 pwl034 N° de réf. du client - Client Ref. No. File No. - N° du dossier N° CCC / CCC No./ N° VME - FMS EQ754-201337 PWL-9-42060 trusses upper structure are still quasi-intact from the 1995-96 paint project, while some parts of the structure below the deck now show important needs of steel replacement due to deterioration. In recent inspection reports, consultants have recommended that PSPC proceed with steel replacement with paint protection to re-establish the steel capacity of those components where deterioration has been identified. A major rehabilitation was completed from 2009 to 2010 which included the following: replacement of the center lane concrete deck including guardrails, strengthening of the truss structure, retrofitting of the superstructure and substructure to live load and seismic capacity, addition of tuned mass dampers, addition of catwalks, replacement of the pedestrians wooden boardwalk and its railings and partial retrofit to the lighting system. The various components of a bridge all have different rates of wear and tear. During the establishment of the scope of work of this 2009-10 major rehabilitation, overall painting of the structure was excluded because PSPC wanted to evaluate the exiting painting system and take on a recommended approach of zone coating as opposed to an overall painting. In 2013-14, the 118 m long north Gatineau Trestle area was strengthened and fully painted through a zone painting contract. The area of Pier 3 along with other specific locations were partially strengthened as part of a contract completed in 2016-17. The present project will concentrate on replacement, strengthening, and coating of steel components in the area of Pier 2, other specific components throughout the bridge and the components removed from the 2016-17 contract. Traffic interruptions on the bridge, on the loading dock of the museum, and on the bicycle/pedestrian path must be kept to a minimum during the contract. Access to the Alexandra Bridge needs to be coordinated with NCC, the city of Gatineau (marina operator), the Museum of History and PSPC. For this steel replacement contract, the scaffolding, enclosure and environmental protection system will need to be erected around and supported by the bridge structure. The area of work is over the Ottawa River. The goal of the present contract is to keep the structure in a safe state of service with a target start date of construction assumed to be Fall of 2021. b) Engineering Services Required — The services required would fall into RS 2.1 Pre- Design Services through to RS 2.7 Post Construction Warranty Review. 1. Your firm has been requested to prepare design for the: (1) Steel replacement to be completed for the steel structure below the roadway deck in the Pier 2 area from floor beam 5 to 14, as well as steel replacement from the tops of pier 2 to the height of the top HSS rail of the center lane deck parapet wall; (2) Within this zone of work, selected components of the steel structure will need to be identified and evaluated for deteriorations and will need to be replaced or strengthened due to loss of section, perforations, cracks and others; (3) Steel replacement or strengthening to specific locations of the structure; and (4) Prepare and administer a zone painting contract for the existing steel within the area of Pier 2. 2. Provide a description of the studies required to complete rehabilitation to satisfy requirements of the CHBDC. c) Take into consideration phasing of project for Health and Safety reasons (time and space separation) in order to minimize traffic interruptions on the bridge, on the loading dock of the museum, and on the bicycle/pedestrian path. d) In addition, provide an analysis of issues, and list studies that would be required prior to proceeding with design development work.
